<h3>LAME 3.90 December 21 2001</h3>
<ul>
<li><font color="#ff0000">Many small improvements and bug fixes not added to
history</font></li>
<li><font color="#ff0000">John Dahlstrom: more fine tuning on the auto
adjustment of the ATH</font></li>
<li><font color="#3366ff">Robert Hegemann: small speed and quality improvements
for the old VBR code (--vbr-old).</font> </li>
<li><font color="#ff0000">Robert Hegemann: some short block bug fixes</font>
</li>
<li><font color="#ff0000">Robert Hegemann: Big improvements to --vbr-mtrh,
now encodes much more frequencies over 16khz</font> </li>
<li><font color="#ff0000">Robert Hegemann: --vbr-new code disabled (outdated
and lower quality) and replaced with --vbr-mtrh (Both --vbr-new and --vbr-mtrh
now default to mtrh)</font> </li>
<li>Robert Hegemann: reordering of --longhelp to give more information,
--extrahelp dropped </li>
<li>Darin Morrison: Totally revamped and extremely high quality unified
preset system and other general quality improvements now available with --alt-presets:
<ul>
<li> <font color="#ff0000">some improvements to psychoacoustics (vast improvements
over default L.A.M.E. modes) when --alt-preset is used including:</font></li>
<ul>
<li> <font color="#ff0000">Improved tuning of short block usage.</font></li>
<li> <font color="#ff0000">Improved quantization selection usage (the
-X modes), now adapts between appropriate modes on the fly. Also helps
on "dropout" problems and with pre-echo cases.</font></li>
<li> <font color="#ff0000">Improved joint stereo usage. Thresholds are
better tuned now and fix some "dropout" problems L.A.M.E. suffers from
on clips like serioustrouble.</font></li>
<li> <font color="#ff0000">Improved noise shaping usage. Now switches
between noise shaping modes on the fly (toggles -Z on and off when appropriate)
which allows lower bitrates but without the quality compromise.</font></li>
<li> <font color="#ff0000">Clips vastly improved over default L.A.M.E.
modes (vbr/cbr/abr, including --r3mix): castanets, florida_seq, death2,
fatboy, spahm, gbtinc, ravebase, short, florida_seq, hihat, bassdrum,
2nd_vent_clip, serioustrouble, bloodline, and others. No degraded clips
known.</font></li>
<li> VBR bitrates are now more "stable" with less fluctuation -- not dipping
too low on some music and not increasing too high unnecessarily on other
music. "--alt-preset standard" provides bitrates roughly within the
range of 180-220kbps, often averaging close to 192kbps.</li>
</ul>
<li> --alt-presets replace the --dm-presets and "metal" preset is removed
and replaced with generic abr and cbr presets.</li>
<li> --alt-preset extreme (note the 'e') replaces xtreme to help eliminate
some confusion</li>
<li> --alt-preset vbr modes now have a fast option which offers almost no
compromise in speed.</li>
<li> --alt-preset standard (and "fast standard") are now much lower in bitrate,
matching --r3mix with an overall average, though offering higher quality
especially on difficult test samples.</li>
<li> --alt-presets are no longer just "presets" as in a collection of switches,
instead they are now quality "modes" because of special code level tunings
(those mentioned above).</li>
<li> Use --alt-preset help for more information.</li>
</ul>
</li>
<li>Roel VdB: more tuning on the --r3mix preset </li>
<li>Jon Dee, Roel VdB: INFO tag</li>
<li>Alexander Leidinger, mp3gain@hotmail.com: added --scale-l and --scale-r
to scale stereo channels independantly </li>
<li>Takehiro Tominaga: <font color="#ff0000">new noise shaping mode, offering
more "cutting edge" shaping according to masking, enabled via -q0</font> </li>
<li>Mark Taylor: More work on --nogap </li>
<li>Gabriel Bouvigne: Small changes to abr code for more accurate final
bitrate </li>
<li>Gabriel Bouvigne, mp3gain@hotmail.com: Preliminary <a
href="http://www.replaygain.org"> ReplayGain</a> analysis code added (not functional
yet) </li>

<h3>LAME 3.89beta July 5 2001</h3>
<ul>
<li> John Stewart: long filename support for Win9x/NT.</li>
<li> Takehiro Tominaga: LAME can calculate the CRC of VBR header, so now

<li><font color="#ff0000">Robert Hegemann: Improvements of the new VBR
code (--vbr-mtrh).</font></li>
<li><font color="#3366ff">Robert Hegemann: New VBR code (--vbr-mtrh) is now
defaulted to get more feedback. The VBR speed is now on par with CBR. We will
use the old VBR code in the release.</font></li>
<li><font color="#ff0000">Gabriel Bouvigne: Change of the maximum frame size
limit. LAME should now be more friendly with hardware players.</font></li>

<li>Mark Taylor: preliminary --nogap support</li>

we will continue to add new functionality. <br>
</li>

band at each iteration.</font></li>
<li> <font color="#ff0000">Takehiro Tominaga: Interframe, shortblock temporal
masking.</font></li>
<li> Takehiro Tominaga: LAME restructured into a shared library and front
end application. Slight changes to the API. More changes are coming
to turn LAME into a true shared library (right now you have to recompile if
you upgrade the library :-(</li>
<li> <font color="#000000">Naoki Shibata:</font></li>
